The 23-year-old joined the Championship club on a season-long loan deal after being told by Reds manager Brendan Rodgers that he will not feature regularly in the first team in 2012-13.
"At this stage of my career, I do need regular football and that's one of the big meetings I had with Brendan," Spearing told The Bolton News. "If I want to push on with my career, I need to play more regularly.
"He sat me down and we had a really good chat. We both told each other the truths of how we thought the season was going to go.
"So, we decided it would be a good experience for me to come out and play some football. I had a few opportunities to go elsewhere but it's not about that now."
Spearing added that he is keen to see Bolton gain promotion to the Premier League.
"I don't see why I can't have a career at Liverpool," he said. "But I am at Bolton now and I want to produce some good games to get us up into the Premier League.
"I am here for the whole season and I think we will be up there fighting.
"I am ready to play for Bolton and I am going to put in 100% every game and try to get as high up the league as possible."
Bolton have picked up just four points from four matches in the Championship so far this season.
